SURFACING MACHINE.

Application filed September 12, 1923.

i To all whom it may concern Be it known that I, CHARLES T. ADAIR, a citizen of the United States, residing at Kansas Citv, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Surfacing Machine; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to surfacing machines and more particularly to a machine for re-surfacing or dressing butcher blocks and the like and the invention consists of certain novel parts and combination of parts all of which will be specifically described hereinafter, reference being had to the accompanying drawings, in which:

Fig. 1 is a perspective view of a surfacing machine constructed in accordance with my invention.

Fig. 2 is a view partly in elevation and partly in section of amachine constructed in accordance with my invention.

Fig. 3 is a sectional view through the gear box and shaft and gears for the saw arbor, and

Fig. -1- is a cross sectional view through the socket member for supporting the machine and the bracket for the socket member.

Referring now to the drawings by numerals of reference 1 designates an elongated socket member having at its upper end a clamping arm 2 to engage the work 3. The socket member is provided with an outstanding lug 4 through which is a draw screw 5 extension. The draw screw also extends through a lug 6 on the jaw member or arm 7 which is sleeved upon the socket member 1. The jaw membe" 7 has an arm or jaw S which engages the underside of the work and the two arms or jaws can be clamped together by turning the draw screw 5 having a threaded connection with the lug 6. When the work is clamped between the members 2 and Sthe draw screw can be locked against turning by the lock nuts 9 and 10, the socket member is closed at the bottom and open at the top. Through the bottom extends an adjustable Serial No. 662,193.

- screw 11 adopted to tbe turned by the hand wheel 12. The adjusting screw can raise and permit lowering of the post 13 which tightly fits the bore of the socket member so that the cutting mechanism can be raised and lowered to determine the depth at which the cut is to be made. The post 13 should fit the socket member like a piston so in order to provide for easy longitudinal movement of the post 13, I provide an opening 14 to prevent the post 13 from becoming air bound in the socket member 1. The bracket '1' is provided with a transverse elongated slot 15 through which the socket member projects and by means of which the socket member is adapted to rock trans versely so as to insure the arms 2 and S to firmly clamp the work, for example the block 3. hen the jaws or arms 2 and have accommodated themselves to the sur faces of the work the socket member can be held rigid by the two set screws 16 and 17. (see Fig. '4). The post 13 is adapted to have a rotatable movement in the socket member and it carries at its upper end a motor block 18 on which is mounted a motor 19, preferably an electric motor having a shaft 20 carrying a pulley 21. Extending through the block and adapted to slide with respect thereto are two longitudinal rods 22 and 23 of a frame consisting of the rods and the two end bars 24- and 25. The end bar 24- is in the form of a gear case and extending through it is a shaft 26 having on its respective ends pulleys 27 and 2S aligning with pulleys 29 and 30 on the shaft 31 tending through the end bar 25. There is an endless belt which extends around the pulleys 27 and 29 and under the idlers 3?) and 34, the-belt passing over the pulley 21 so that when the motor is driven the belt will be driven and it in turn will drive the shafts 26 and 81, due to the fact that the belt passes over the pulley 27 and 29. There is a compensating belt 3 1 which passes around the pulleys 28 and 30 so as to equalize the stresses exerted on the shafts 26 and 31. when the motor is operated. The two belts 32 and 34: impart motion to the shaft 26 and the shaft 26 carries a beveled gear 35, the gear 35 meshing with a gear 36 on the saw arbor 37 which passes through the hollow bar or gear case and which carries at its lower end a circular saw horizontally disposed so it can take off the surface of the block or other work upon which it is oper-- ating. A frame is adapted to slide longitudinally through the block 18 so that the saw can be moved back and forth over the work and due to the fact that the post 13 has a rotatable movement in the socket member, it is observed that the frame can be swung on an are so it may travel over the entire surface of the block to be dressed. On the shaft 31 is an air impeller or fan within the casing 38. The casing has an inlet communicating with the pipe 39 having a nozzle 40 adjacent to the saw,-and the fan casingdischarges into'a fabric container or bag ll so that when the maehine is operating the saw dust will be drawn through the tube 39 and discharge into the bag or container 41. The frame can be swung by the handle 42.

It will be apparent from the foregoing that the frame can have a longitudinal and swinging movement so the saw can operate over the entire surface of the block to redress it and that the construction is such W that the device can be inexpensively manufactured and applied to the work.

What I claim and desire to secure by Letters-Patent is:

1. A surfacing machine comprising :1

socket member having a jaw at one end, a sliding jaw on the socket member co-operat ing with the first named jaw to clamp the socket member to the work, the slidable jaw having an elongated slot, set screws in the slidable jaw for engaging the socket member so that the slidable jaw can be held in tilted position and surface dressing mocha nism carried by the socket member.

2. A surfacing machine coi'nprising a socket member having a jaw at one end, a sliding jaw on the socket member eo-operating with the first named jaw to clamp the socket member to the work, the slidable jaw having an elongated slot, set screws in the slidable aw for engaging the socket member so that the slidable jaw can be held in tilted position and surface dressing mechanism rotatable about the axis of the socket membeer and supported thereby.

3. A surfacing machine comprising a socket member having a rigid ja at one end, a tiltable sliding jaw on the socket member means for holding the tiltable sliding jaw rigid with respect to the socket member and a surface dressing mechanism carried by the socket member.

In testimony whereof I afiix my signature.

CHARLES T. ADAIR.
